The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。 Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.

The revolution of automation on factory floors is a key driver for the seemingly insatiable demand for higher productivity, lower total cost of ownership,and high safety. As a result, industrial applications drive an insatiable demand of higher data bandwidth and higher system-level performance. This white paper describes the trends and challenges seen by designers and how FPGAs enable solutions to meet their stringent design goals.

在实际应用中,编程者往往喜欢程序能自动生成word说明文档,说明程序运行的状况或运行的结果;或者程序能提取数据库的内容生成word表格,使用户能方便的查看和修改,打印。但是VC++中调用word的确不容易,特别是对word中各种函数的使用,本文以作者的工作经验详细介绍一下如何调用word和进行word表格的填写,有同样需求的编友也可查看一下MSDN中的automation Microsoft Office 97 and Microsoft office 2000。

操作系统有所耳闻,它是微软已推出的三种操作系统内核之一,是一种实时操作系统。虽然它是一种实时操作系统,但是从96年发布v1.0到现在,它的主要用途都在民用领域,比如Pocket PC、SmartPhone、automation。不像VxWorks,应用于航空航天、军事等领域。现在linux、VxWorks厂商也都看好嵌入式民用市场,激烈竞争在所难免。我看好Windows CE,因为微软在PC领域实在太强,用户也早已熟悉了微软的产品,把PC下的技术移植到嵌入式领域,首先在操作界面方面就占了上风。

我们在编写程序,开发软件的过程中如果能利用已有的程序的功能,那么可以大大减轻开发过程中程序员的工作量,同时达到事半功倍的效果。例如在工程中,许多软件需要文字处理功能,虽然MFC提供了一些方法,但是具体实现起来既费事,又有一定的困难,如果我们可以直接使用OFFICE提供的功能,岂不美哉!要实现这一目的,只需要利用微软的ActiveX automation技术就可以轻松实现。本例主要讲述了自动化的概念,并通过一个操作Word文档的程序来帮助读者朋友理解Visual C++编程中如何实现自动化。
